The correct answer is Salinization.

• Salinization is an increase in the total dissolved solids (TDS) as the salt of the aquifer caused by natural or anthropogenic factors.
• Salinization is a global problem.
  • It tends to be concentrated in the world’s arid and semi-arid regions.
• Gypsum (calcium sulfate) or lime can be used to help leach salt from the soil.

Important Points

• Desertification is an environmental degradation that reduces the productivity of dryland ecosystems by reducing plant.
  • Overgrazing is the major cause of desertification worldwide.
  • Other factors that cause desertification are urbanization, climate change, overuse of groundwater, deforestation, natural disasters, and tillage practices in agriculture that make soils more vulnerable to wind.

• It ended in a victory for Alexander’s Macedonian Army.
• Large areas of Punjab were subsequently absorbed into the Macedonian Empire.
• Hydaspes River is now called the Jhelum River, a tributary of the Indus River.

Punjab literally means "(The Land of) Five Waters" referring to the following rivers: the Jhelum, Chenab, Ravi, Sutlej, and Beas which flow through it.

Ravi River, in northwestern India and northeastern Pakistan, one of the five tributaries of the Indus River that give Punjab (meaning “Five Rivers”) its name.

Beas River, Beas also spelled Bias, Sanskrit Vipasha, river in Himachal Pradesh, and Punjab states, northwestern India. It is one of the five rivers that give Punjab (“Five Rivers”) its name.

The Beas rises at an elevation of 14,308 feet (4,361 meters) at Rohtang Pass in the western (Punjab) Himalayas (a section of the vast Himalayas mountain range), in central Himachal Pradesh.

Two streams namely Chandra and Bhaga rise on the opposite sides of the Baralacha pass at an elevation of 4,891 meters and meet at Tandi at an elevation of 2,286 meters to form the river Chenab. The Chenab rises from the South-East and Bhaga from the North-West of the Baralacha pass.

It enters the Pangi valley of Chamba district near Bhujind and leaves the district at Sansari Nala to enter Podar valley of Kashmir. It flows in Himachal for 122 km. With its total length of 1,200 km., it has a catchment area of 61,000 sq. km., out of which 7,500 sq. km. lie in Himachal Pradesh.

It is the largest river of Himachal Pradesh in terms of volume of waters. The Chenab valley is a structural trough formed by the great Himalayan and Pir Panjal ranges

The correct answer is All of the above.

• Sound is the main means of communication in many animals, including humans. A low sound is pleasant and harmless. A loud, unpleasant, or unwanted sound is called noise.
• Sources of Noise Pollution:
  • ​​Industrialization: Most of the industries use big machines which are capable of producing noise.
  • Poor Urban Planning: In most developing countries, poor urban planning also plays a vital role.
  • Social Events: Noise is at its peak in most social events.
  • Transportation: A large number of vehicles on roads, airplanes, trains produce heavy noise.
  • Construction Activities: Construction activities like mining, construction of bridges, dams, buildings, stations, roads, flyovers take place in almost every part of the world.
  • Fireworks: Firework is a common thing during various fairs, festivals, and cultural ceremonies

Additional Information

Effects of noise pollution: 

• Auditory effects:
  • ​Deafness or impaired hearing: Prolonged exposures to noise lead to gradual deterioration of the internal ear and subsequently hearing loss or deafness.

Noise level in dB = 10Log₁₀ (Noise in watts)

10 dB = 10Log₁₀ (Noise in watts)

Noise in watts for 10 dB = 10¹ = 10 Watts …(1)

1dB = 10 Log₁₀ (Noise in watts)

Noise in watts for 1 dB = 10^0.1 = 1.26….(2)

P₁/P₂ = 10/1.26 = 7.94 W

• The hardness of water is that characteristic that prevents the formation of sufficient leather or foam.
• It occurs due to the presence of carbonates, bicarbonates, sulphates, chlorides of calcium and magnesium(Ca and Mg).
• The hardness of water is due to the presence of dissolved minerals of Ca2+, Mg2+, Al3+, Iron and other heavy elements. Specifically due to Calcium Sulphate, Calcium Bicarbonate, Calcium chloride, Magnesium Sulphate, Magnesium Bicarbonate and Magnesium chloride.​

• The heat is transferred in form of conduction, convection, and radiation. 
• Radiation is the mode of heat transfer that does not require a medium. It happens through infrared radiation. 
• The infrared radiations are electromagnetic waves having a frequency less than the visible spectrum. 
• The infrared radiation is emitted from every hot body. 
• Earth is heated by infrared radiations of the sun. The radiations are reflected back by the earth which is captured by greenhouse gases. 
• The greenhouse gases absorbers some amount of heat and keeps the earth warm. 

Thus, infrared radiation is trapped on the earth’s surface by the greenhouse effect.

Additional Information

• The major Greenhouse gas is Carbon dioxide followed by methane, water vapor, and nitrous oxide.  
• UV rays have a frequency higher than violet and they help in the formation of Ozone. 
• The wavelength of different electromagnetic waves are given in the below diagram. 

The total distance = 15 + 20 + 30 + 15 = 80m

Hence, the correct answer is 80m.

The first pair shows two states of matter and the second pair gives examples of those states

- Given Codes:
- PAINT = 74128
- EXCEL = 93596

- Analysis:
- Each letter is represented by a single digit in the code.

- Mapping:
- P -> 7
- A -> 4
- I -> 1
- N -> 2
- T -> 8

- Applying the same logic to ACCEPT:
- A -> 4
- C -> 5
- E -> 5
- P -> 7
- T -> 8

- So, the code for ACCEPT is 455978, which corresponds to option A.

From the final arrangement, we get “C sits at one of the extreme ends".
Hence, Option D is correct.
References:
O sits 3^rd to the right of N.
One who sits just behind O is to the immediate right of E.
Inferences:
From the above reference, we get the following cases:

References:
B is neither at any of the extreme ends nor sits exactly behind O.
The number of people sitting between C and E, is the same as the number of people sitting between E and B.
Inferences:
From the above reference, we get the following cases:

References:
D doesn’t sit at any of the extreme ends.
P sits on a seat which is exactly ahead of A.
M is not exactly ahead of E.
Inferences:
From the above reference, we get the following cases:
Case 1: Position of D cannot be fixed, thus this case is eliminated.

Case 2: We get the final arrangement as below:

Hence, option A is correct.

Hence the option B is correct

Either you can make a fraction from two whole numbers (denominator ≠ 0), thus a rational number. Or you can't, thus irrational.

Using Rule 1 :
1st number × 2nd number = L.C. M. × H.C.F,
First number × Second number = HCF × LCM

Given, 3, 8, 13, 18, … is the AP.
a = 3
d = a(2) – a(1) = 8 − 3 = 5
Let a(n) term be 78.
a(n) = a + (n − 1) x d
78 = 3 + (n − 1) x 5
75 = (n − 1) x 5
(n − 1) = 15
n = 16

As we know that the angles are supplementary so sum of angles will be 180 degree.
Let us assume that the ratio factor is r.
According to question,
Angles are supplementary and have a ratio of 1:4.
r + 4r = 180
⇒ 5r = 180
⇒ r = 180/5
⇒ r = 36

use formula:1/2(sum of of parallel sides)(distance between them)

3.14 x 10⁶ = 3.14 x 1000000 = 3140000.

Total Mango trees = 40%

Remaining trees = (100 – 40 – 50)% = 10%

Hence, Option B is correct.
